FEEDING DEVICE FOR MATERIALS Original application led December 10, 1927, Serial No. 239,156. Divided and this application flied I October 23, 1928.

My invention relates to feeders for materials but refers more particularly to feeders for coal, stone or chemicals where an even feed is required and more especially to stationary feeding devices.

One object of myinvention is to provide a device for feeding materials which has an adjustable cutting off knife or blade.

Another object of my invention is to provide a material feeder that combines a rotating disc, an adjustable knife feeder and a dust proof driving means.

This application is divisional of the application filed Dec. 10, 1927, Serial Number 289156.

Disc feeders with Scrapers delivering the materials from the center of the disc to the outside as heretofore produced would be unsuitable for feeders on movable machinery such as railroad locomotives, and ships at sea, as the rolling motions or jars due to sudden stops or associated with such use would allow the materials fed to slide from the bin over the disc to the floor.

Disc feeders heretofore used allowed a certain amount of material to pass off the disc, wherein this particular device is provided with a cylindrical band surrounding the disc feeder except where the material is delivered to the spout, said band independently supported.

The band around the disc may be either supported from a stationary part of the disc feeder or from a swinging arm and may be made adjustable for taking care of the wear on the band and the disc. Y

It is well known in the art that disc feeders have been used but none contemplate the unique combination of novel elements utilized in producing the remarkable results obtained by this particular device.

With these and other objects in view, my invention consists of the novel construction, arrangement of partsand formation of the same, hereinafter referred to and described, claimed and substantially as illustrated in the accompanying drawings, wherein similar numerals refer to like parts throughout the several views, in which 1- Serial No. 314,152?.

Figure 1, is a partial cross section of the kdisc feeder.

Figure 2, is a plan, partly in section of Figure 1, taken on lines 2-2 of Figure 1.

Figures l and 2, illustrate the disc feeding device utilizing a revolving disc and which carries the material from the center of the disc over the edge or periphery from whence it is conveyed as desired.

A swinging arm is mounted on the central axis of the apparatus permitting the swinging of the knife from one side of the feeder to the other and away from the spout, enabling the operator to catch a sample for a given number of revolutions of the disc which may be weighed and thereby the weight or the quantity by bulk being cut from the disc per revolution may be determined so as to indicate the quantity of ppaterials being fed per minute, hour or ay.

This rotary disc feeder is comprised of a base 58, with a bearing 59, carrying a shaft 60, the upperend of which is attached to `a disc 61, by the set screw 62, and this bearing 59, has a flanged casing '68, integral thereof, which contains the driving mechanism.

The driving mechanism comprisesa motor 64vwhich may be driven at variable speeds, connected to a driving shaft 65, by the coupling 66, said shaft running in the bearings 67 and 68, carrying a worm 69, which. meshes with a worm wheel 7 0, on shaft 71, also carrying a worm 74, meshing with a worm wheel 75, heldv to the shaft 60, by the' set screw 76. Y v v This casing 63, extends above the driving mechanism and projects into a groove 77, integral with the disc 61, thus preventing fdust from entering into the casing 63.

Adjacent to the periphery of the disc 61, is a retaining ring 78, broken away at 79, f and supported by a multiple of supports 80.

The adjustable supports 80, comprise a casting 81, which is attached tothe ring78, by the bolts 82, said casing being supported by the rod 83, threaded at 84, to allow for adjustment when the ring 78, wears away.

Material is fed to the center of the disc 61, on

from the bin or receptacle 85, to which is bolted a flanged pipe 86, by the bolts 87, and

to this pipe 86, is adjustably attached a pipe 88 for controlling the height of the material delivered on the disc 61, and this adjustment is accomplished by means of the bolts 89 and nuits 90.

' The material isrmoved from the center of the disc 61, by means of the blade 91, bolted Wheel 101by means of the set screw 102.

Lil

The bearings 97' and 98, are part of a U shaped Vcasting 103, Which is bolted by the bolt 104C, to an arm 105, adjustably held to the base 58, by the bolts 106 and 107.

The Whole apparatus may be fastened to any suitable place by means lof' bolts, not shown, Which'may pass through the holes 108, andthe motor 64, or any other suitable driving means may be fastened to a bracket 109, by the bolts 110, and the bracket fastened in anysuitable manner to the base 58. Y

In operation, material isA fed ,from the source of supply 85, through the pipe 86, and the heightof the pilev on the disc 61,

Y regulated byfadjusting the pipe 88, {Whereupon the blade `91, When suitably adjusted will direct material through the opening 7 9,
